S32K116 GPIO emulate I2C

[zhangzhiyong]

We used the S32K116，we need two I2C（baudrate reach 400K），but S32K116 has only one LPI2C.

The other one can，we want to use the flexio emulate IIC，but the flexio’s transmission length is Limited to 13 bytes.

Can you provide a program：GPIO emulate IIC，baudrate reach 400K？

Hello,

Unfortunately, we have no GPIO emulate IIC example code for the S32K devices.

However, there is an application note for the S12/S12Z devices which could be used as inspiration:
